Well worth owning, I've caught this movie on AMC several times in the last few years. An excellent entertainment from a highly competent craftsman, a piece of Second World War propaganda that has stood the test of time. One of the credited screenwriters was Dorothy Parker, and her wit is evident in much of the dialogue. (The everyman Robert Cummings character to the high-class Nazi Otto Kruger--"We'll fight people like you! Fight to the end! Fight! We'll fight until the cows come home!") Hitchcock was above all a popular artist, (his "Vertigo" notwithstanding), and this is the director at his very best.
